Is there no one in Regina that has a VP100 or 150 that you could audition? If not how about a road trip to Calgary where there has been an explosion of Axiomites lately, I would gladly give you an audition.
I think the VP series is a little cleaner, crisper sound than the Paradigm CC. So you may find you actually like a center once you've had a chance to hear one of them.
So far as music goes unless listening to multichannel, the center won't add much and none if you have the receiver in stereo mode. For movies it helps, as John said, to keep the dialogue centered, but if you are not going to be off axis much then the phantom modes in the receivers works quite well.
I am surprised John didn't mention trying a vertical center speaker like the M2 or M3 or if you have room another M22 for the center channel to see if you like that better.
